ALIGNING BIM WITH FM: STREAMLINING THE PROCESS FOR FUTURE PROJECTS ON THE PENNSYLVANIA STATE UNIVERSITY CAMPUSES

Abstract: A study performed by the National Institute of Standards and Technology (NIST) in 2004 found that owners account for approximately $10.6 billion of the $15.8 billion total inadequate interoperability costs of U.S. capital facility projects in 2002. Because of these inefficiency costs, it becomes vital that information produced during the design and construction phases of a project be transferred into operations with maximum leverage to the end users. However, very few owners have defined these informational needs or developed an integration strategy into existing maintenance management systems. To increase operational efficiency, an organization must first develop an understanding of their operating systems, as well as identify how Building Information Modeling (BIM) will add value to their daily tasks.The Pennsylvania State University (PSU) has a unique opportunity to diversely implement BIM processes because not only does the University act as an owner, but also as designer and construction manager on the majority of projects. The struggle that PSU faces is one that is unique only to owners with a large, existing, multifaceted building inventory. This paper outlines the current initiative by the Office of Physical Plant (OPP), the asset manager at PSU, to develop an information exchange framework between BIM and FM applications to be used internally. Specific topics to be ascertained are: the research steps taken to develop a strategic implementation plan for information exchange process between project stakeholders and the OPP; an overview and gap analysis of the existing operations processes currently implemented; and a summary of the collaboration effort between vendors, project stakeholders and the OPP to develop this information integration. As a result of this research, PSU has been able to define owner operational requirements for future projects and develop a flexible integration framework to support additional BIM tasks and information exchanges.

An Immersive Virtual Reality Mock-Up For Design Review Of Hospital Patient Rooms

Abstract: Having identified a scarcity of evidence-based design principles and practices for patient-centered healthcare environments, researchers at the Purdue University Regenstrief Center for Healthcare Engineering have developed a Virtual reality (VR) mock-up of a hospital patient room to explore its efficacy for identifying how physical environment and design elements impact behavior, processes and safety. The VR patient room mock-up is designed to have a high degree of interactivity to facilitate evaluation of the designed space as a “healing environment.” Positive feedback from healthcare practitioners regarding the mockup has motivated the Investigators to leverage their experience to create VR mock-ups for other hospital units and venues.

Application of Immersive Virtual Reality Systems in an Interdisciplinary Design Studio Course

Abstract: The architectural, engineering, and construction (AEC) industry has been witnessing a recent growth of application of visualization and virtual reality technology for design reviews. As our future generations of designers and engineers enter the industry, they will have to possess the ability to leverage such technology. This study aimed at evaluating the experience of students from an interdisciplinary design studio course, in performing internal design reviews with two different types of display systems. The research aimed at understanding which systems the students found most valuable, immersive, and enjoyable when visualizing their models. The first system utilized was a semi-immersive three screen display system, while the second was a single screen large LCD television system. The participants included five groups, with students from different disciplines, such as architecture and architectural engineering. The groups were randomly split into two tracks and took part in an ABBA experimental procedure. The studentsŐ responses were collected through a survey, which was administered after they reviewed their design with each system. Based on the findings, the researchers were able to conclude that the utilized semi-immersive display system promoted the studentsŐ sense of immersion, spatial presence, and enjoyment, over their regular collaboration pod using an LCD screen.

Semantic tags for collaboration in construction formalized within a social network framework

Abstract: As construction projects require tracking an ever-increasing number of parameters to operate with suppliers, vendors, and the entire organization of a construction firm, particularly in exchanging, sharing, and integrating information, a semantically rich form to represent information is required. Semantic tags for interoperable construction workflows represent a novel approach to support the exchanging, sharing, and integrating of information. This approach proposes a semantic main form of representation of construction concepts to assist in the communication between actors. The proposed approach is based on the notion of the social network framework. The assumption is that construction actors’ relationships in communicating information can be expressed by patterns of relationships defined in a social network structure. Semantic tags leverage the communication of information within the dynamic social network grid by employing a concept-description that contains metadata. The purpose is to semantically enrich the product or project data. It is expected that the inclusion of additional semantics will overcome inefficiencies within interoperability.

The suitability of IT as a tool to facilitate knowledge sharing in construction alliances

Abstract: The impact of environmental pressures has led many organisations to combine their resources and form alliances to develop and sustain competitiveness, profitability and long term growth. A review of the literature suggests that construction firms are not significantly different from others in their behaviour in meeting up the challenges imposed by the environment. Trends of forming strategic alliances therefore have embraced majority of the sectors of the construction industry. Not only do alliances act as vehicles for efficient project management but also they provide the opportunity for the organizations to share participants' knowledge. In this paper, which is based on an ongoing study, we argue that IT could be used as a tool to leverage shared knowledge in alliances to improve organisational outcomes. Indeed the traditional belief among people that "knowledge is power", which inhibited intraorganisational knowledge sharing, continues to act as a major constraint in alliance knowledge sharing too irrespective of the degree of IT use. In this paper we demonstrate the use of IT to complement other socialisation mechanisms to create new knowledge. In the process we investigate the effectiveness and efficiency of knowledge transfer mechanisms and link organisational outcomes to new knowledge creation.

an approach to Impact Assessment of ICTs for Energy Efficiency

Abstract: The importance of information and communication technologies (ICTs) as an enabler for energy efficiency is well understood, however there is no one agreed common methodology for assessing the impact of ICTs on energy efficiency. In order to promote legitimacy, transparency and real progress in the application of ICTs to improving energy efficiency there is a clear need for common ways of assessing energy performance based on a common understanding of commitments, targets and methodology. In this paper, common means for assessing the impact of ICTs on energy efficiency are reviewed and the approaches of organisations focused on the development of ICT impact assessment methodologies are discussed. Subsequently, a potentially useful means of qualitative impact assessment is suggested. The proposed methodology aims to leverage the heuristics of domain experts and is based on life cycle thinking coupled with elements of an adapted capability maturity model/framework. The SMARTT taxonomy developed as part of the overall approach for common assessment is also described. SMARTT stands for Specification and design, Materialisation, Automation and operational decision support, Resource and process management, Technical integration and Trading/transactional management. Aligned to these six high level categories are twenty sub-categories to which user-defined ICTs/research and technology developments (RTDs) are mapped. An impact assessment example is given to illustrate how the proposed approach can be used at the offering level. The SMARTT taxonomy and common methodology are deemed by the authors to be as a useful means of assessing the impact of ICTs on energy efficiency both within and across sectors and potentially offers a foundation on which to base more quantitative methods to assess the impact of ICTs on energy efficiency.

Tomorrow's workday: spontaneous, creative, and reliable

Abstract: Through several scenarios, this paper shows how a construction project manager might spend a workday in the future. The particular tasks addressed include participating in a design review meeting, preparing the construc-tion input to an engineering issue, tracking the schedule, budget, and environmental performance on a project under construction, dealing with organizational issues around innovative methods, and maintaining the company’s intelligent production planning and control system. Through these examples, the paper also tries to show that the combination of lean production methods and virtual design and construction tools should not only lead to reliable workflow, but should also enable and leverage the ingenuity, spontaneity, and creativity of designers, engineers, and builders.

United States Air Force Milcon Transformation: Building Information Modeling Case Studies

Abstract: The United States Air Force manages approximately $2B of traditional military construction (MILCON) per year in a typical portfolio of 100-150 projects. In Fiscal Year, 2010, the Air Force’s MILCON authority having jurisdiction, the Air Force Center for Engineering and the Environment (AFCEE) revised its standard design instruction to supplement how it managed and directed MILCON. One of the primary differences was a requirement for all vertical construction to be designed through a Building Information Modeling (BIM) approach. There were two pilot projects to assess Air Force BIM implementation. First, one project case study explored impact on typical MILCON project management practices. The HQ CENTCOM facility implemented a BIM-based approach on a standard design-bid-build project at MacDill Air Force Base, FL. A second project case study explored cutting edge research methodologies that used the BIM for facility optimization on a LEED-platinum facility. Specifically, the Tyndall Air Force Base Fitness Center targeted energy efficiency. The facility’s Electronic Management Control System (EMCS) monitored pure consumption, solar photovoltaic (PV) power meter pulse output, and solar hot water recovery systems using Digital Energy Monitors (DEM) tied to the BIM via an exported database file via the EMCS server. Lastly, AFCEE partnered with Onuma to manage and leverage their new BIM-based designs to afford greater collaboration from inception onward for USAF facilities worldwide. This research investigates owners’ lessons learned and designers’ experiences related with the initiative under MILCON Transformation, as well as the implications for shaping future USAF MILCON management and design optimization.

A scalable working model for cross-disciplinary global teamwork education

Abstract: Our mission is to prepare the next generation of architecture, engineering, construction (AEC) profes-sionals who know how to team up with professionals from other disciplines and leverage the advantages of innovative collaboration technologies (ICT) to produce higher quality products, faster, more economical, and environmentally friendly. To achieve this mission we have been offering the AEC Global Teamwork course established at Stanford in 1993 in collaboration with universities worldwide. The AEC Global Teamwork course was described in many previous papers. This paper examines this course as a scalable working model for cross-disciplinary global teamwork education. More specifically we discuss the following dimensions: (1) a growing global learning network, (2) expanding the cross-disciplinary engagement, (3) evolving ICT EcoSystem, and (4) increasing number of social worlds students distribute their attention.

4D-PS: Putting an IT new work process into effect

Abstract: A leading, international, engineering and construction company has carried out efforts to engage a new tool set and work process. Four-Dimensional Planning and Scheduling (4D-PS) is the new work process that aims toward better, more efficient planning and execution of large construction projects. This paper describes the case history and forecasts how this revitalized technique may ultimately impact the construction industry. Despite academic and practitioners' research and development efforts to leverage from Information Technology (IT) in construction, the industry at large, being generally conservative, has adhered to the values of predictability and existing methods to minimize risk. 4D technology has struggled to find its way into mainstream construction practice for several years, and just recently it has been shown that commercially available software and hardware can be applied effectively toward this end, greatly reducing investment risk. These relatively new tools promise new impetus to the use of 4D-PS in the construction industry. This paper describes how 4D-PS was applied on a major construction project, giving rise to a new work process that proved to be productive and cost effective. Emphasis is made on the fact that those expected to use such technology must have the necessary training and, conversely, near-future versions of computerized tools can be made more intuitive for more widespread use. The use of such techniques will necessarily draw engineering/design and construction entities closer together, essentially improving coordination among them.
